Sanchez, a federal prisoner confined at Leavenworth, Kansas, under multiple, unexpired sentences imposed in the District of Puerto Rico for various narcotic offenses, petitioned in the District, of Kansas for habeas corpus and the writ was denied on the ground that the remedy under 28 U.S.C. § 2255 was ex-r elusive. We agree. The § 2255 remedy is exclusive unless it is inadequate or ineffective. The only showing is that a motion under § 2255 in the sentencing court was unsuccessful. That is not enough. Barrett v. United States, 10 Cir., 285 F.2d 758, 759; Williams v. United States, 10 Cir., 283 F.2d 59, 60. The denial of a motion made under § 2255 does not, of itself, establish that the remedy provided by that section is either ineffective or inadequate.

Affirmed.
